​​​Have it your way – Produce your own enzymes locally and minimize their operational cost

Biorefinering processes converting residual biomass into value added fuels and chemicals are advancing rapidly across the globe. Biochemical biorefineries rely on powerful cellulase enzymes to hydrolyze biomass into sugars, which can then be further converted into the desired end product. These enzymes are expensive and non-recyclable, therefore representing a significant cost barrier to the broader deployment of biorefinery concepts.

In this webinar we take a deep dive into the industrial cellulase production process, understand why cellulases are expensive and how alternative manufacturing processes can significantly cut the operational cost represented by enzymes.

We will take a look at the current global scenario of cellulosic biorefineries and define four alternative models for enzyme production – centralized, near-site, on-site and integrated. Each of these models comes with certain benefits and drawbacks, but there are some indisputable advantages in taking enzyme production down to the biorefinery level. No one transports yeasts to biorefineries to run fermentations, so why should enzymes be any different?In this talk, we will look at cellulase production using Trichoderma reesei and break down enzyme cost into 5 key contributing factors:

Nutrient price

Fermentation yield

Fermentation productivity

Enzyme processing and logistics

Hydrolysis performance

We will see how each of these 5 factors influences overall enzyme cost and how different enzyme production models in turn influence these factors. For all the 5 factors, we will also discuss the available technical tools to minimize their cost impact. To attain minimal enzyme operational cost, which levers should be pulled and how
